Let's talk about the effect of humic acid.

I have always thought that many fishery drugs such as detoxification are deceiving the common people, the expensive ingredients are nothing more than VC, glucose, etc., almost, such as zeolite powder, humic acid, and so on, and there are a lot of products with many names, a company can have seven or eight kinds of bottom changes, what cool bottom changes, detoxification base changes, water transfer base changes, oxygen-added bottom changes, and so on. How to solve this poison and how to change this land? What problem can humic acid solve? let's talk about it. Attachments: you need to log in to download or view attachments. No account number? Registration-indeed, there are only a few ingredients that are useful. It's just a bluff from the manufacturer for publicity. The modification should be based on active agents, such as photosynthetic bacteria, Bacillus, yeast and so on. And then there are things like humic acid and fulvic acid that have been fermented-- yes, there are a lot of concepts in aquatic products, but some things are not, and every company still has a little formula. Or secret-the landlord is too dark, casually find some information on the Internet to come here and ask for money? Humic acid is a kind of macromolecular compounds with complex components, which can be divided into three components according to their solubility to different solvents, namely fulvic acid, fulvic acid and black humic acid. Humic acid is widely found in lignite, weathered coal and peat, with a content of 30% to 70%. In the 1970s, China set off an upsurge in the research and application of humic acid, mainly to solve the shortage of fertilizers in agricultural production at that time. Humic acid plays a special role in plant growth because of its biological activity and special structural properties. The organic acid substance provided by humic acid in natural coal is called MFA, and the humic acid substance produced by our first biochemical method is called BFA (BiotechnolosyFulvicscicl). This green technology in line with environmental protection provides a larger platform for the application and development of humic acid products. At present, humic acid has been used in agriculture and forestry, medical and health, petroleum, building materials, environmental protection, pesticides, fertilizers and other industries. Especially with the strengthening of people's awareness of environmental protection and the prevalence of green health food, humic acid will play an important and unique role in solving this problem and providing these edible substances. as a result, humic acid will have a broader market space. it will also promote the faster development of this product and industry. At present, there are few reports on the application of humic acid in aquaculture in China. Some discussions and comments are made here. 1 Aquatic feed additive 1.1 Biological activity mechanism the main elements of humic acid are carbon, hydrogen, oxygen, nitrogen and sulfur, which is a condensation polymer of polyvalent phenolic aromatic compounds and nitrogen compounds. The molecular weight distribution is wide, with a small molecular weight of tens of thousands and a large molecular weight of tens of thousands to millions. The structure and composition is also very complex, including phenolic hydroxyl group, alcohol hydroxyl group, quinone hydroxyl group, enol group, sulfonic acid group, amino group, free quinone group, semi-quinone group, quinoxy group, methoxy group and so on. The components are entangled by chemical and physical interactions such as bonding, hydrogen bonding, adsorption and so on. The existence of these active groups determines the acidity, hydrophilicity, ion exchange, complexation and high adsorption, buffer and catalytic capacity of humic acid. The addition of humic acid to the feed can effectively absorb all kinds of toxic and harmful substances produced by the storage of the feed, and can also absorb the toxic substances produced by digestion and metabolism in the process of digestion and metabolism. Such as: amines, hydrogen sulfide and other substances to maintain the normal intestinal microflora. Humic acid added to feed can also be used as a drug and has a significant therapeutic effect on intestinal ulcer and gastritis. As humic acid contains small molecules of fulvic acid, it can adhere to the surface of ulcers and quickly stop bleeding, which is conducive to rapid tissue healing. Humic acid can enhance the immunity of animals, and can promote antigen uptake, cellular immunity and humoral immunity in the immune process. Humic acid containing quinone can participate in the redox reaction of the body, maintain exuberant metabolism and promote cell proliferation. Humic acid can also act on the autonomic nervous system, can inhibit the excitement of the sympathetic nerve, make animals quiet and reduce consumption. Because humic acid is a kind of organic acid, it can regulate the pH value of digestive tract, promote the secretion of digestive enzymes in young animals, activate the activity of various enzymes in the body, change the permeability of cell membrane, improve the absorption of feed nutrients and improve the utilization rate of feed. promote growth and development. For biochemical fulvic acid, it contains not only humic acid, but also a certain amount of nucleic acid, amino acid, VB, VC, inositol and polysaccharides. It is not only a strong biological activity, but also an important nutrient for animals. In short, according to clinical proof, humic acid has the characteristics of hemostasis, anti-inflammation, pain relief, convergence, adsorption, anti-allergy, promoting secretion, regulating gastrointestinal function, improving body immunity and enhancing animal disease resistance [5]. At present, in order to cater to the consumer psychology of farmers, improve animal growth and pursue feed effect, some feed manufacturers have added a large number of antibiotic drugs to the feed, which directly affect people's health due to the residue of antibiotic drugs. As a green environmental protection product, humic acid can be added to feed instead of antibiotics. In recent years, scientific research shows that humic acid, as a new type of feed additive, has peculiar efficacy, plays a very important role in breeding, and will promote the development of feed industry. 1.2 Application in Aquatic Feed processing and production Aquaculture has special requirements for feed production because of its special aquaculture environment. First of all, the particle density is small and has a suspension effect in water. However, to meet this condition, feed in the granulation production will result in a decrease in the adhesion of particulate ingredients, resulting in easy crushing in the process of product transportation, a decrease in the consumption rate of feed for fish or shrimp, and an increase in breeding costs. The application of humic acid will solve this problem very well. Humic acid has colloidal properties and has a good adsorption and bonding effect. It also shows a loose structure in the water. At present, the Russian aquatic feed processing and production industry has a good application of humic acid and advanced technology. The feed processing technology in China is still relatively rough, especially the research on the production technology of seawater particulate feed has just started. According to relevant data, the Institute of Oceanography of the Chinese Academy of Sciences has made a major breakthrough in the processing and formulation of seawater particulate feed. It is believed that the success of this technology will better promote the development of aquaculture. Application of humic acid in aquaculture the effect of humic acid in aquatic bait is reflected in the following aspects: ① increases the utilization rate of bait, feed conversion rate increases by about 10%, and the growth rate of ② is accelerated. For example, in the culture of Penaeus Monodon, the culture time is shortened by nearly 1/4, and ③ has the effect of drug synergism. With the addition of appropriate amount of BFA in aquatic feed, the morbidity and mortality of fish and shrimp were greatly reduced, and the anti-stress ability was also significant; ④ can improve meat quality. Zhanjiang Ocean University and Zhanjiang Fubang biochemical Co., Ltd. conducted experiments on the application effect of humic acid in shrimp culture for 2 years in Nansandao culture area. The results showed that the yield was increased significantly, and the yield was up to 80~100kg per mu. Jiangxi Pingxiang Fisheries Institute added 0.5% humic acid to the feed, tested grass carp and chain fish, the weight gain rate increased by 17.6% and 24.3% compared with the control, and the survival rate increased by 15%. And the phenomenon of undead fish during the culture period was tested. Humic acid also has the same special effect in other livestock and poultry breeding [6], such as: Hungarian humic acid as an additive, quality pigs grow to 110kg, the breeding time is shortened by one week. In fishery, the yield increased by 16.3% in eel culture. The laying hens were tested in Beijing Dongfeng Farm, and the addition amount was 0.3%. The laying rate increased by 26.98%. Experiment on fattening shelf pigs with humic acid in Zhanjiang Institute of Agricultural Sciences. After 60 days in the first stage, the relative weight gain rate was 17.2%, and the weight gain in the second stage was 25%. Beijing Dongfeng Farm tested female mink and young mink. Compared with the control group, the weight gain rate of female mink was 32%, the weight gain rate of young mink was 27.3%, and the methyl skin was 32.5% higher than that of the control group. In a word, humic acid, as a special feed additive, has played a significant role in aquaculture. 2 conditioning and purification of aquaculture water quality and bottom reform the quality of aquaculture water quality environment is an important link in the success of aquaculture, fish culture is the first water culture is this truth. In recent years, with the development of aquaculture technology, in order to increase the yield per unit area, high-density aquaculture technology is widely used. in this way, the amount of feed per unit area will be greatly increased, because the consumption rate of feed is not very high. When the remaining high-protein feed sinks to the bottom, it will ferment to produce toxic and harmful substances such as H2S, ammonia nitrogen and nitrous acid. At the same time, it also increases the content of organic matter in the water. The existence of these substances will seriously affect the growth of fish or shrimp, and the mortality will increase. The light ones will reduce production, and the heavy ones will be wiped out, and there will be no harvest. If this happens in the middle and later stages of breeding, the loss is relatively heavy. At present, the main methods of water purification and bottom improvement in aquaculture are as follows: ① is adsorbed and precipitated by zeolite powder and other polymerized iron or aluminum salts. Because zeolite powder contains a large number of micropores, it can absorb ammonia nitrogen, H2S and other heavy metals in the water, making it sink at the bottom and reducing the distribution in the water body of the reservoir. The use of inorganic polymer is to use the hydroxide colloid produced by it to adsorb the organic suspended matter in the water body and precipitate at the bottom of the pond to improve the transparency. The use of ② microbial preparation is a new way to purify and improve the water quality of aquaculture. For example, photosynthetic bacteria can make full use of harmful substances in water, as well as other organic pollutants as nutrients for cell growth and reproduction. Using photosynthetic bacteria, the removal rates of ammonia nitrogen, chemical oxygen demand (COD) and biological oxygen demand (BOD) were 66%, 94% and 98%, respectively. The fact that humic acid can be used for water purification and bottom modification in aquaculture is determined by its special structure and properties. Humic acid has the property of colloid and shows loose structure in aqueous solution. In addition, humic acid contains a variety of active groups, so it has strong ion exchange ability, adsorption, complexation and chelating ability. According to the electron microscope observation of Flaiy et al, the smallest dispersed particle of humic acid in water is 6~10nm, so the humic acid particles and other particles adsorbed by them will agglomerate and produce flocculent precipitation, which can purify the suspended organic matter in water and improve the transparency of water quality. Humic acid contains a variety of active genes that can complex harmful heavy metals in water and purify water quality through enrichment and precipitation. The pH value of mariculture water is generally 8.08.5, and humic acid contains phenolic hydroxyl groups. The complexation principle of humic acid is the complexation of humic acid with metal ions. Beck-With has used potentiometric titrator to sum up their stable order, namely Pb2+ > Cu2+ > Ni2+ > Co2+ > Zn2+ > Cd2+ > Fe2+ > Mn2+ > Mg2+. In shrimp breeding, the Institute of Oceanography of the Chinese Academy of Sciences conducted a study on humic acid to relieve the toxicity of heavy metals to young shrimp. It was found that humic acid could purify water quality, relieve the toxicity of Pb2+, Cu2+ and Zn2+ to young shrimp, effectively promote the growth of young shrimp, increase the survival rate by 14%, get out of the pool ahead of time, and be strong, dynamic and neat. Zhanjiang Ocean University and Zhanjiang Fubang biochemical Co., Ltd. studied the effect of humic acid on clean water transfer and bottom modification in Nanshan Island shrimp culture area. The results showed that when 1 5kg humic acid was applied per mu, the water quality was stable for more than 10 days, the transparency was kept at 30~40cm, and the water body showed the feeling of "fat, alive, tender and cool". Shrimp has strong appetite, strong physical strength and fast growth rate. Through the control experiment, during the 15-day interval, the weight gain rate of the first stage was 18.3%, and that of the second stage was 21.6%. For biochemical fulvic acid, its molecular weight is small, in addition to 50% humic acid, there will be 15% nucleic acid, 25 amino acids (9%), VB, VC, inositol, polysaccharide and so on. These active substances have high physiological activity to organisms. Therefore, these substances can promote the growth of beneficial microorganisms and unicellular algae in water, and the growth of these organisms can increase the amount of dissolved oxygen in water. At the same time, it also provides natural food for shrimp. (3) the development prospect of humic acid as a new type of green aquatic feed, humic acid is also increasing at the rate of 8%. Humic acid used in aquaculture is seldom reported in China at present. As a natural active substance, humic acid can be used as disease prevention agent instead of antibiotics in a certain range. The development of humic acid has a broad market prospect. The problems existing in humic acid industry, such as small production scale, relatively backward technology, unstable quality, weak technical strength of enterprises, insufficient development and application research, thus restrict the development of this industry. The mechanism of humic acid is not well understood and needs to be further studied in order to improve the wider application space and value of humic acid. -- when is this information? Please speak, seniors. I'm here to learn. Can you tell me what color fermented humic acid sodium is? I haven't seen it. Are you talking about what it should be like in layer feed? What's the use? Sodium humate (NaHA) characteristics: dark brown powder, soluble in water, the amount of water solution is alkaline. Quality index: water soluble humic acid content (dry base),% ≥ 50 45 water insoluble,% ≤ 15 25 water,% ≤ 15 fineness (through 40 mesh sieve)% ≤ 5 P H value 9: 10 uses: this product is widely used as viscosity reducer and filtrate loss reducer in drilling fluid, temperature resistance can reach 200 ℃, but the disadvantage is weak salt resistance. At present, putrefied sodium has been widely used as an additive in various industries, such as ceramics, feed, mineral processing, pellet bonding, industrial water treatment and so on. Medicine is also being developed and used, such as the treatment of some skin diseases. Therefore, sodium humate is used more and more widely. Packing: woven bags for external use, plastic film for office use. Precautions for 25kg/ bag: strictly guard against damp and rain. Sodium humate is a kind of macromolecular organic matter which exists widely in nature. It has large reserves, but it has not been fully exploited. At present, the relevant departments have paid attention to the development of this resource. Compound sodium humate is a new type of feed additive, which integrates the interaction of humic acid, sodium humate, citric acid and Hawthorn extract, which has a very significant effect of antibacterial and anti-inflammation, convergence and anti-diarrhea and improving production performance. Sodium humate has been widely used in the breeding industry of pigs, poultry and herbivores in China. Sodium humate can restrain diarrhea, promote growth and improve animal production performance. In addition, sodium humate has many advantages, such as extensive resources, low price, easy to use, obvious effect, no drug residue and so on, so the application prospect of sodium humate is broad. Jiang Anwen (1) it has been reported in 1999 that many feeding experiments have proved that sodium humate improves the production performance of animals. 1. Application of Wang Neigui ⑵ in chicken industry in 1981, a self-made compound livestock and poultry growth aid based on sodium humate was used to test 404 laying hens of the same age. The test group added 1 g sodium humate additive every day, and the egg laying rate of the test group was 24.5% higher than that of the control group. The effects of sodium humate on laying rate, plasma composition and egg nutritional composition of laying hens were studied by ⑸ of Haidian District Animal Husbandry and Fisheries Bureau of Beijing. 1016 experimental chicks were selected. the experimental group was fed with 1.5 ‰-2 ‰ (calculated by pure quantity) and the content of sodium humate was 79%. The results showed that the average weight gain of each chicken in ⑴ within 80 days was 85.6g and 7.6% higher than that in the control group, and the difference was significant (P
